Continuity mistake: In the "Krazy Kripples" episode in Season 7, Jimmy's last name is given as Swanson. In "Up the Down Steroid" in Season 8, it's changed to Jimmy Vulmer.
Continuity mistake: When Jimmy is talking about Christopher Reeve and Superman while the boys are on the ground playing with toy cars, Stan looks up at Jimmy and says 'Yeah that's nice guys. Were going to stay out of this one.' When the camera cuts to another angle, Stan's head is in a different position.
Answer: He appears in at least 5 other episodes, but usually just as a background character. He can be seen at Cartman's party in "Immaginationland". He was also one of the kids trying out to replace Butters in the "Professor Chaos" episode.
